Application filed September 26, 1910. Serial No. 583,910.

Be it known that I, BERTRAND P. B own, a

of Wilkinsburg, in the county of Allegheny and State of Pennsylvania,have invented a new and useful Improvement in Methods of Making TerminalDevices, of which the following is a specification.

My invention relates .to terminal members for cables and otherelectrical conductors, and it has for its object to provide a simple andeflective method of forming a terminal member that shall have a highcurrent-carrying capacity and shall present a large area'for engagementwith parts to which it 1 is connected.

A terminal member has heretofore been provided for electrical conductorswhich consisted of a tube-having one open end forthe reception of thecable or other conductor and its other end flattened for engagement withthe part to which theconductor is connected. In order to permit of readyattachment of the terminal member to the said part, the flattenedportion is usually perforated and the area presented for engagement withthe said part is often thereby sog represents a blank from which theterminal member is made. Fig. 2 represents the' ter-v minal in itssecond stage of manufacture. 1

ing the enlarged end.

I Fig. 3 represents the terminal in the third stage-of'manufacture. Fig.4 is a face view of acom'pleted terminal, and Fig. 5 is'a side view of-acompleted terminal.

The blank from which the terminal member is made consists of a tube,such as shown in" Fig.- 1, that is composed of copper or other suitableductile material. The blank is first expanded at one end, as shown inFig. 2, or its ends may be otherwise caused to have different diameters,as by swaging and reducing one end. The larger end of the blank, asshown in Fig. 2, is next flattened, as shown .in Fig. 3, and is finallyperforated and. trimmed, as shown in Figs. 4 and 5. I

By reason of the enlargement of the flat tened end of themember, withrespect to the unfiattened end, the annular portion of the flattened endpresents suflicient area, for engageme'n-t. with parts to which themember.

is connected, to permit of conduction of current from the said part tothe cable or other conductor without overheating and undue drop ofpotential.

I claim as my invention: 1. The method of forming a terminal member thatconsists in enlarging one end "of a tube and then flatteningand-perforat- 2. The method of forming a terminal member that consistsin causing a sheet metal tube to differ in diameter at its ends and;then flattening and vperforating the larger end.

In testimony whereof, I have hereunto subscribed my ber, 1910.
